Title: Potential finger print detecting method
Inventor: MASUKO KENZO
IPC: A61B5/117
Filed: 1989-06-27
Abstract: PURPOSE:To detect the image of a finger print in a simple manner without deterioration and/or decomposition of a substrate by bringing the potential finger print left on a subject in contact with a nascent ruthenium tetroxide gas in the potential finger print detection for the criminal investigation. CONSTITUTION:Sheets of filter paper are impregnated is respective ruthenium chloride solvent and cerium nitrate ammonium solution separately, and they are dried thereafter. When used, they are put into a small container in mutually over-lapped relation so that ruthenium tetroxide gas is produced with water added. Then the small container is gripped by a hand so that ruthenium tetroxide gas is thereby spouted out of a polyethylene tube 3 furnished with a check valve 4. Then, it is brought into contact with the potential finger print left on a substrate (subject) while it is changed into a black compound of ruthenium dioxide so that the potential finger print is thereby actualized. By this constitution, the finger print can thereby be detected very sensitively in a simple and safe manner at low cost.

Title: Optical transmission module
Inventor: YAMAGUCHI SHOICHIRO
IPC: G02B6/42
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To enable a long distance optical transmission and a high speed optical transmission by providing an optical member which is provided so that its focal position is positioned at the light emission end face of a light source having a waveguide structure and which coverts outgoing from the light source into lights whose parallelism are high transmits the lights and a multimode fiber which receives lights transmitting the optical member. SOLUTION: Since an optical lens 20 is provided so that the focal position of it is positioned at the light emission end face of a light source 10, both light beams of a direction whose aperture angle is large and a direction whose aperture angle is small in among light beams 50b are both converted into light beams 50c whose parallelism are high in the lens 20 to be made incident on a multimode fiber 40. As a result, higher-order modes are not generated at the incident end of the multimode fiber 40 and in lights propagating the fiber 40, only lower-order modes whose parallelism are high are made to be made incident on the fiber and lights whose propagation speeds are lined up are made to propagate through the fiber 40.  Thus, an optical transmission module capable of performing the optical transmission of a longer distance and a higher speed as compared with the conventional optical transmission midule is obtained.

Title: Measuring method for characteristic of electronic circuit
Inventor: SUZUKI KOUICHI
IPC: G01R31/26
Filed: 1979-12-14
Abstract: PURPOSE: To increase the accuracy of measurement for the characteristic of the part to be evaluated, by irradiating the light to the speicified part of an electronic circuit and thus varying the temperature of the specified part.  
     CONSTITUTION: The terminal 4 functions as an electrode of a resistance contact with a semiconductor substrate and is also connected metallurgically to an external lead wire. The differential temperature change characteristic is measured for the voltage between the gate and the source while being drived by the same drain current and in the state in which the laser beam or the infrared ray is irraditated to the external lead wire. In other words, when the light is irradiated to the external lead wire, the FET chip connected metallurgically to the lead wire via the terminal 4 has its temperature increased suddenly. Thus the temperature of the chip is measured in an extremely high accuracy in the general bias state corresponding to the amount of change of the gate-source voltage of the FET at the single side.
